  The connector 1 having the above-described configuration is assembled as follows. First, an operator holds the electric wires 15, 15 a, 15 b on the electric wire holding part 9 provided in the cover part 8, and routes these electric wires 15, 15 a, 15 b in a U shape. And the bending part 15d of the electric wire 15 wired innermost is cut | disconnected, and it forms in the said electric wire 15c.

  Next, the control circuit package 6 is inserted into the housing body 7 through the opening 12. At this time, of course, the male tab 21 is positioned in the hood portion 10, and the standing portion 24, that is, the press contact blade 20 is positioned at a position standing from the bottom wall 11 a of the control circuit package housing chamber 11.

  Subsequently, the cover 8 is gradually brought closer to the opening 12. Then, the electric wires 15 a, 15 b, 15 c held in the electric wire receiving groove 14 of the electric wire holding portion 9 are gradually inserted into the slits 25 of the corresponding standing portions 24 of the press contact blade 20.

  When the engaging portions 13 a and 13 b are engaged with each other and the cover portion 8 completely closes the opening 12 and is attached to the housing body 7, the electric wires 15 a, 15 b and 15 c are in the slit 25 of the press contact blade 20. The press contact blade 20 cuts the covering portions of the electric wires 15a, 15b, and 15c and comes into contact with the core wire.

  Thus, the connector 1 having the above-described configuration is assembled. The connector 1 assembled in this way is a hood portion 10 that fits into the mating connector 2 in the same manner as a general connector composed of a terminal metal fitting and a housing that have been used conventionally and does not contain an IC chip 17 or the like. The electric wires 15a, 15b, and 15c are drawn from the back side as viewed from the side. The connector 1 described above is engaged with the mating connector 2 to form a wire harness 29 as shown in FIGS.

  In the wire harness 29, an electrical connection box 31 is attached to the ends of the electric wires 15a, 15b, and 15c via the connector 1. In the wire harness 29, power from the power source is supplied to the IC chip 17 via the power source wire 15a, and the switch signal of the switch 30 connected to the connector 2 of the other party is transmitted via the IC chip 17 and the control wire 15c. And transmitted to the electrical junction box 31. Thus, in the connector 1, the IC chip 17 connects the electric wire 4 attached to the mating connector 2 and the electric wires 15a, 15b, and 15c press-contacted to the press-contact blade 20 according to a predetermined pattern.

  When disassembling the assembled connector 1, first, an operator pulls the electric wires 15 a, 15 b, 15 c away from the housing body 7 and removes the electric wires 15 a, 15 b, 15 c from the housing main body 7. At this time, the connection between the electric wires 15a, 15b, 15c and the press contact blade 20 is released, and the engagement between the engaging portions 13a, 13b is released, so that the cover portion 8 is brought together with the electric wires 15a, 15b, 15c. It is removed from the housing body 7. Then, the control circuit package 6 is removed from the control circuit package housing chamber 11 of the housing body 7 through the opening 12. As described above, the connector 1 is easily disassembled.

  According to this embodiment, the electric wire holding part 9 is provided on the back side of the hood part 10 that is fitted to the mating connector 2, and the electric wires 15 a, 15 b, and 15 c are arranged along the mating direction K of the mating connector 2. Since it is held, it can be handled in the same manner as a general connector that does not incorporate the IC chip 17.

  For this reason, as shown in FIGS. 8 and 9, the connector 1 can be arranged at the ends of the electric wires 15 a, 15 b, 15 c, that is, the ends of the branch lines of the wire harness 29, and thus the wire harness 29 provided with the connector 1. Even when assembled with a wire harness provided with a general connector, it can be routed to an automobile or the like in the same manner as a wire harness provided with a general connector. Therefore, the connector 1 can be handled in the same manner as a general connector conventionally used when assembled to the wire harness 29, and can be easily handled.

  Further, since the electric wire holding portion 9 is provided in the cover portion 8, the electric wire holding portion 9 can hold the electric wires 15 a, 15 b, 15 c and the cover portion 8 can be assembled by simply attaching it to the housing body 7. Therefore, the connector 1 can be easily assembled. Moreover, since the cover part 8 can be removed from this housing main body 7 by pulling away the electric wires 15a, 15b, and 15c from the housing main body 7, the connector 1 can be disassembled easily.

  Furthermore, since the control circuit package 6 includes the press contact blade 20, the control circuit package 6 and the electric wires 15a, 15b, and 15c can be easily connected. Therefore, the connector 1 can be assembled more easily. Further, since the connection between the control circuit package 6 and the electric wires 15a, 15b, and 15c can be easily released, the connector 1 can be disassembled more easily.

  Further, since the power supply wire 15 a and the grounding wire 15 b are bent and arranged in a U shape in the outer housing 5, the power supply wire 15 a and the grounding wire are connected between the plurality of connectors 1 of the wire harness 29. The electric wire 15b can be shared. Therefore, increase of the electric wires 15a, 15b, 15c constituting the wire harness 29 can be suppressed.

  Further, since the control wire 15c for cutting the bent portion 15d is arranged closer to the center than the power supply wire 15a and the grounding wire 15b, the curvatures of the power supply wire 15a and the grounding wire 15b are arranged. The radius can be increased, and the control electric wires 15c separated by cutting the bent portion can be brought close to each other.

  For this reason, since the curvature radius of the electric wire 15a for power supplies and the electric wire 15b for earth | grounds can be enlarged, it can prevent that the electric wire 15a for power supplies and the electric wire 15b for earth | grounds are cut off unexpectedly. Further, since the control electric wires 15c separated by cutting the bent portion 15d can be brought close to each other, the outer housing 5, that is, the connector 1 itself can be reduced in size.
